Marshal.GetTypeLibGuid Method (ITypeLib)

Retrieves the library identifier (LIBID) of a type library.

Namespace:  System.Runtime.InteropServices
Assembly:  mscorlib (in mscorlib.dll)

static member GetTypeLibGuid : 
        typelib:ITypeLib -> Guid

Parameters

typelib
Type: System.Runtime.InteropServices.ComTypes.ITypeLib

The type library whose LIBID is to be retrieved.

Return Value

Type: System.Guid
The LIBID of the specified type library.

GetTypeLibGuid extracts the LIBID directly from an existing type library. This action differs from that of the Marshal.GetTypeLibGuidForAssembly method, which calculates what the LIBID should be based on the current assembly.

For more information about library identifiers, see Exported Assembly Conversion.
